CQRDAGE-SPINNING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 404,137, dated May 28, 1889.

Application filed March 30, 1888. Serial No. 268,995. (No model.) 7

To all whom it may concern.-

Be it known that we, ANTON WVEBER and CLEMENT LAMBERT, of Elizabeth, in the county of Union and State of New Jersey, have invented a new and useful Improvement in Cordage-Spinning Machines, of which the following is a full, clear, and exact description.

This invention relates to a cordage-spinnin g machine; and it consists in an improvement thereon whereby the operation of the machine is automatically stopped if the cord breaks, and the machine cannot be started until the bobbin upon which the twisted cord is wound is securely mounted upon its spindle.

The invention will be set forth in the following description, and pointed out in the claims.

Reference is to be had tothe accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side View of a portion of the cordage-spinning machine, partly broken away and in section. Fig. 2 is a plan view on line x w of Fig. 1. Fig. 3 is aplan view of a detail,with parts broken away, showing a portion of the spindle onwhichthebobbin is mounted and the safety device for holding the spindle in place. Fig. 4 is a detail plan view of the bracket at the end of the capstan-tube,with parts broken away, and a portion of the automatic stopping device. Fig. 5 is an end view, with parts broken away, and in cross-section of the machine looking from right to left in Fig. 1. Fig. 6 is an end view,with parts broken away, of the machine looking from left to right in Fig. 2. Fig. 7 is a detail view, with parts broken away, of a bobbin safety device; and Fig. 8 is a detail view of the spindle-stop shown in Figs. 3 and 6.

1 indicates the framing of a portion of a well known form of cordage spinning machine, having mounted therein the usual dri ving mechanism, consisting of the main shaft 2, having bevel-gearing 3 at one end thereof connected by a shaft, 4, witha fast pulley, 5, and a loose pulley, 6,which are driven by means of a. band, 7, leading to any suitable power. The main shaft 2has at its other end a pulley, 8, connected by aband, 9,with a pulley, 10, in which is mounted the well-known capstan-tube receiving the cord 11 from the nippers and condenser. (Not shown.)

The twisting and windin g mechanism is of the usual construction, and maybe briefly described, as follows:

12 indicates the flier, and 19 its operatingpulley.

14 is a sliding shaft passing through the sleeve 15 of bracket 16 and through the sleeve 17, carrying the bobbin 13 to the outer head, 20, of the flier.

18 is the pulley on the bobbin-sleeve 17. The pulleys 18 and 19 are driven by belts 21 from the main shaft 2.

In order to shift the driving-belt 7 from the fast pulley 5 to loose pulley 6, and vice versa, the following mechanism is employed: At the end of the frame 1 is mounted, in brackets 23, a transverse sliding bar, 24, having pins 25 projecting at right angles thereto on either side of the driving-belt 7. Any suitable shifting-lever may be connected with bar 24 to start and stop the machine by hand.

To automatically stop the machine when the cord breaks, the following mechanism is connected with the belt-shifting mechanism: The sliding bar 24 is provided with a depending arm, 25, having an oblong slot, 26,which is engaged by a pin, 27, on the lower end of a lever, 28, mounted on a shaft, 31, from which extends an arm, 29, having counterweight 30. The shaft 31 extends lengthwise through the frame 1, and is provided with a depending arm, 32,which connects at its lower end by a pin, 40, with the inner shoulder, 42, of a lever, '35, pivoted to a bracket, 36, on the the frame 1.

Mounted in adjustable brackets 37 on the frame 1 is a shaft, 38, which hasa depending arm, 39, with a pin, 33, engaging a notch, 34, of the lever 35. On the shaft 38 is also mounted a lever, 43, extending horizontally therefrom, and pivot-ally connected at its end with a vertical rod, 44, eccentrically pivoted to an arm, 45, pivoted to a bracket, 46, on the frame 1 adjacent to the pulley 10, in which ismounted the capstan-tube, through which the cord passes from the nippers and condenser. (Not shown.) The shaft 38 carries at its end beyond lever 43 the common and well-known shifter-arm, which acts on the 49 does not exert a great force to draw the arm 45 against the cord 11. The arm 45 is prevented from falling backward or away from the cord 11 by means of the pin 45'.-

The operation of automatically stopping the machine in case the cord breaks will now be described.

Upon the cord 11 breaking, the arm 45,which gently bears against the cord 11, will drop over toward the left, and by means of the action of the spring 49 the lever 43 will be pulled down, thereby causing the shaft 38 to be turned, and with it the arm 39, which throwsthe latter outward, and by means of the pin 33 lifts the lever 35, releasing the notch 42 from the pin 40. By this means the arm 32, upon which the pin 40 is mounted, is permitted to have free movement, and being mounted on the shaft 31 is rotated with it by means of the counterweighted lever 29,which drops downward and swings the arm 28 to one side, and by means of the connection with the pin 27 in the oblong slot 26 pushes the arm 25' to one side and carries with it the sliding bar 24, thereby, on account of the pins 25 projecting from the sliding bar 24, shifting the driving-band 7 from the fast pulley 5 to the loose pulley 6 and causing the driving mechanism to stop.

It being often necessary to remove the winding-bobbin 13, and there being liability to accident owing to careless replacing of the bobbin, the following device is employed: To remove the bobbin 13, the shaft or spindle 14 is slid laterally until it is disconnected from the bobbin 13. It has been found that in replacing the bobbin the shaft 14 has been hastily and carelessly slid back, so that its end did not slip into its bearing 20, and the machine then being started an accident ensued. In order to prevent the machine from being started until the bobbin is securely mounted on its spindle, the following device is employed: A slide, 51, provided with a handle, 52, is mounted in the bracket 16. When the rod or spindle 14 has been pushed into place and the slide 51 dropped down over the outer end of the spindle 14, the latter is thereby held from being drawn out.-

To one of the brackets 23 is pivoted alever, 53, formed with an angular portion, 54, and connected at its other end, 55, with a rod, 56, having a hooked end, 57, adapted to engage thehandle 52. When the machineis in operation, the lever 53, the rod 56, and the slide or guard-piece are in the position shown in Fig. 6, the lever 53 being out of contact with either of the pins 25. Upon thedriving-belt7 being shifted to the loose pulley 6 and the machine stopped and it is desired to remove the bobbin 13, the slide or guard 51 is raised, carrying with it the rod 56, and raising the lever 53, so that its angular portion 54 is brought against the outer pin, 25, which has been carried to the right by the movement ofthe slidebar 24 when the machine has been stopped, the position being shown in Fig.7. The lever 53 will be held in engagement with the pin 25 by means of the slide or guard 51 resting on the spindle 14, as shown in Fig. 1. By this means it will be seen that the machine cannot be started until the lever 53 is released from the pin 25. This latter can only be effected by pushing in the spindle 14 until the slide or guard 51 is permitted to drop past the endof the spindle 14. The bobbin will then have been securely mounted on its spindle, and the machine may then be started by pushing the bar 24 to the left and shifting the driving-belt7 to the fast pulley 5. By means of this invention upon the breaking of the cord the machine will be automatically stopped, and cannot be started until the bobbin is securely mounted in place;
